Preferably a sheet of noni-abrasive material 22, such as soft leather, is fitted across the' upper side of member 15 between flangesnl'l tcr avoid scarring the impressed sole 14. Y s

In using the novel device above described, a previously cemented lastedlupper and sole are juxtaposed in their proper relationship. Mem'- ber 15 is then positioned beneath the 'sole with ange 17 embracing theperiphery'thereof. This assembly is then placedin the press with diaphragm 11 engaging member l5 andy means 12 holding the lasted. upper against upward `displacement. The pressure isgthen increased to the desired extent, usually by linflatingthe pad beneath the'shoe. VDiaphragm 11 will thenl press upwardly toward the shoe with a uniform pressure at all points on such diaphragm, and its exibility will cause it to adopt-'a configuration substantially as shown in Fig; 1.' Force is transmitted directly through the slightly ilexible element 18 tothe central part of sole 14, thus holding the latter ina flat non-bulging position and causing'a firm pressing engagement between the sole and upper throughout such area. Since element 15 isof such extent that it approximately reaches to the contact line between the upper and the sole, Yfulladhesion is assured,l marginal pressure being transmitted through element 18 and *member 16. Slight pressure may also be appliediagainst the sole through the marginal portion-'20 of member 18, as a result of the direct engagement of diaphragm 11 with the outer part :of such margin 2.0, but lany tendency to curl or rollv the marginal portion of 'the sole is resisted bythe` inherent rigidity of member 16.

The nexibility of element 181s 'such that the device is suiciently responsive to deforming forces to adapt itself tothe desire/d conguration. Thus, it may be bent fairly readilyto conform to the contour of the usual shoe sole, soas to ypress closely against theflat central portion thereof, jand yet follow receding `portions such as the shank. Any pronouncedrolling ofthe sole edges is effectively 'precluded howeven by applying pressing forces theretoV in the above described manner. f v

It will be seen that the flanged guard 15, can be made in. various sizes, and that the guards interchangeably used with a number of different Ypresses and shoes.
